GM OIL LIFE SYSTEM - RESETTING
The GM Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a Service Engine Oil message being turned on, reset the system.

After changing the engine oil, reset the system by performing the following steps:
1. With the engine off, turn the ignition key to "ON".
2. Fully press and release the accelerator pedal slowly two times within five seconds.
3. Turn the key to "LOCK". If the "Service Engine Oil" message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.
